Evidence of reliability and validity of the Brazilian Portuguese version of the Jefferson Scale of Attitudes Toward Interprofessional Collaboration.

Interprofessional collaboration leads to better health outcomes. Measuring attitudes related to interprofessional collaboration is not a simple task, and in Brazil, there are few instruments for this evaluation. This study aimed to evaluate the evidence of validity and reliability of the Brazilian Portuguese version of the Jefferson Scale of Attitudes Toward Interprofessional Collaboration in a population of undergraduate healthcare students. It included 108 undergraduates from medicine, nursing, physiotherapy, dentistry, pharmacy, psychology, and physical education academic programmes. The median age was 22 (18 and 58) and 75% were females. The scale comprises 20 items divided into two domains: working relationships, consisting of 12 items, and accountability, consisting of 8 items. The instrument showed good reliability (Cronbach's alpha = 0.77, 95% CI 0.71-0.83) and no item was considered inconsistent in improving the scale significantly. The scale demonstrated good evidence of validity and reliability for application among a population of Brazilian healthcare students.
